being shown for the purpose of illustration. Owing to the very convenient eonstructimi, however. one or more additional outlets may be provided, if desired.

The two outlets shown consist of tubular extending parts (3, to'which are connected the discharge' pipes T, the discharge bei controlled by suitable valves arranged in the valve casings 8, which valves are operated 1 l) (I?! w/m'm, it may com-em: I

Be it known that. I, Hanur l). ()rrnm siding at Chicago, in the and State of Illinois, have invented c ertain new and useful, Improvements in Tank- Closures, of which the following is a description.

My invention belongs to that class of deeounty of Cook vices known as sausage stutlers or the like, by handles 0, or their eipiivalents. The and relates particularly to an improved stutter. head is also Pl'OVit ed withan air vent, which is provided with a stem 11 and beinga spring for normally maintaining the valve upon its seat.

The closure is pi votally secured to the receptacle and arranged to be first raised and then swung transversely of the receptacle in opening, and swung transversely, and then lowered in closing. The raising and lowering is necessary where thecooperating bead and groove 2' and 4: are employed. The 010- sure is extended as at 15 and secured on a shaft 16 by a key 17 and nut 18, or the equivalent. The shaft 16 is shouldered as at 19, and thence extended as at 20 through two cars 21 and 22, arranged on the side of the receptacle. A pin 27 extends through the shaft, part 20, being extended to form closure for sausage stutling, or similar machines, having among its objects the production of a device of the kind described that is simple, convenient, etl'ieient, safe and satis-' factory, and that may be employed wherever found applicable.

The present invention is in the nature of an improvement on the closure shown in the application of Edward L. Gross, filed August 30, 1911, Serial Niunber (516,849.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and dc scribed, and more particularly pointed out. in the claim.

In the drawings, wherein like. reterencd characters indicate like or corresponding parts," Figure 1 is a sectional view taken substantially on line 1. 1 of Fig. 2 of a sausage an operating handle or lever 2). The pin stutter, and Fig. 2 15}! top plan view of the or shaft 27 is provided with cams 28 and same, 31, which cooperate with hearing plates 24 and'23, arranged as shown. As shown in the drawings, the cover is.locked in position on one side by the cams bearing against the plate If it is desired to open the receptacle by removing the: closure, the handle 29 s grasped and turned so that the cams bear against the plate 24, and consequently lift the shaft 20 and the closure. As soon as the closure is raised sufficiently the shaft 16-20 is rotated by means of the: handle or 'lever 29w, swinging the closure 'froml over the reccptacle. The closure may be locked in position iipon the receptacle in any suitableor desired, manner. The cams lock one side, as previously described, and to lock the same at other points, locking bolts 38 extend through or past the ears -41 on the receptacle. and handled nuts 40 Referring to the drawings, in which the stufi'er receptacle or tank and the closure are shown, 1 represents the body of the stutter, or that is the tank or receptacle. VVit-hin the receptacle is arranged a piston or plunger 5, the same being preferably air admitted through the inlet it, The stutter tank is perfectly smootlron tliein; side, so that the plunger or meat follower is positively air tight, water tight and meat tight T-limopen end of the casing or receptaele is provided with the removable closure or cover 3, the parts being provided with a cooperating bead and recess. affording a tightfit, suitable means being employed for locking the closure in position when desired. As shown, the head 2 is provided on the end of the receptacle, and the may be provided. This isfully described cover 3 provided with the cooperating in the apphcatnon previously mentioned.

The present invention lies particularly in groove 4. Arranged in the closure are any an improved closure, it being understood desired number of discharge outlets. two

that the raisin and swinging means just described may able. 'As shown, the extending part 15 of the closure 3 is extended as at 25 to form what may be termed an auxiliary closure, so that when the closure is in its open position or in an intermediate position, the extended part 25 will extend over the edge of the receptacle when any portion of the closure 3 does not. This is indicated by the dotted lines in Fig. 2. The extension is intended to prevent theplunger from being thrown out of the receptacle at any time, for instance, should the compressed air be accidentally turned on when the closure 3 is swung away from the top of the receptacle. closure 25, or some part thereof, always overlaps or overlies the receptacle end, the plunger 5 cannot be removed or thrown out without removing the closure from the shaft The auxiliary closure also serves to some extent as a counterbalance for the closure 3, relieving the shaft 16 from strain. Where it is desired to swing the closure 3 in the opposite direction to that shown, the handle 291s removed and positioned to extend at the opposite side of the device. For this reason I have made the auxiliary closure substantially uniform in diameter. It may, however, be designed to overlie the receptacle only during the normal throw of the closure '3.

Having thus described my invention, it is obvious that various immaterial modifications maybe made in the same without de- Since the closure 3, or the auxiliary parting from the spirit of my invention,

hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement or. combination of parts herein shown and described, or uses menioned.

What I claim as new and desire to secure by Letters Patent is An apparatus of the character described comprising a vertically arranged cylindrical receptacle having an inlet adjacent its lower end for compressed air, a followerurranged in air-tight engagement with the inner wall of the receptacle, a closure for the upper'end of the receptacle having an outlet opening, said closure being supported from the outside of the cylinder for swinging movement, and the inner surface of the cylinder forming an unobstructed passageway for the follower from top to bottom thereof, and an auxiliary closing medium on the closure adapted to overlie the open upper end of the receptacle as the closure is swung to open position, whereby the said cooperating closures form a stop at all times limitin the outward movement of the follower due to the air pressure therebeneath.

In testimony whereof, I have hereunto signed my name in the presence of two subscribing witnesses.
